Heat resistance of epoxy plastics

Based on the results obtained, the method of estimating the deformation heat resistance of samples of microplastics with the Perkin—Elmer TMA-7 is recommended. The method combines simplicity of sample preparation with high sensitivity. For the epoxy binders studied, the position of the epoxy plastics with respect to the level of heat resistance coincides both based on the criterion of preservation of strength and preservation of rigidity.
